Below the preferred embodiment of model utility is described in further detail.
As shown in Figure 1, a kind of embodiment's transmission device, comprise: driving mechanism, the first friction wheel 11, the second friction wheel 12, elastomer 8 and rotating shaft 18, driving mechanism is used for driving the first friction wheel 11 to rotate, rotating shaft 18 is through the second friction wheel 12 and the first friction wheel 11, the second friction wheel 12 has the friction race 121 coordinating with the first friction wheel 11, rotating shaft 18 and the second friction wheel 12 are fixing, elastomer 8 is for the first friction wheel 11 is applied to the elastic force towards the second friction wheel 12, so that the first friction wheel 11 stretches at least partly in friction race 12 under this elastic force.
Wherein, driving mechanism can be common driving mechanism, and such as drive the first friction wheel 11 by driving sources such as motor or cylinders, the driving sources such as motor can drive the first friction wheel 11 by transmission device, such as driving belt and drive link etc.In one embodiment, driving mechanism can be as shown in Figure 1, comprise motor 2, speed reducer 3, speed reducer output shaft 4, speed reducer belt wheel 5 and belt 6, motor 2 drives the first friction wheel 11 to rotate by speed reducer 3, speed reducer output shaft 4, speed reducer belt wheel 5 and belt 6.
Elastomer 8 can be spring, has flexible rubber, have flexible PVC＝polyvinyl chloride etc., especially take and there is flexible rubber, there is flexible PVC＝polyvinyl chloride etc. as good, the elastomeric material of this class is softer, when colliding with the first friction wheel 11, can not sound, thereby can guarantee that the peace and quiet of whole transmission device and pass gates move.In one embodiment, elastomer 8 can be arranged in rotating shaft 18, and can be butted on the bounding means (or this bounding means is a part for rotating shaft 18) that is fixed on rotating shaft 18 ends in one end; Elastomer 8 even can be arranged on beyond rotating shaft 18, and for example one end is butted on the bounding means that is fixed on the first friction wheel 11 tops, and the other end is butted on the first friction wheel 11, so that the first friction wheel 11 is applied to above-mentioned elastic force.Therefore, the mounting type of elastic component 8 is not limited to the mode of the embodiment shown in Fig. 1.And transmission device comprises adjusting nut 7 in the embodiment in figure 1, the end of rotating shaft 18 arranges screw thread, and rotating shaft 18 is threaded with adjusting nut 7, thereby the two ends of elastomer 8 are butted on respectively adjusting nut 7 and the first friction wheel 11.The elastic force that adjusting nut 7 applies for adjusting 8 pairs of the first friction wheels 11 of elastomer, thereby the degree that can regulate the first friction wheel 11 and the second friction wheel 12 to engage.
Between the first friction wheel 11 and rotating shaft 18, can have bearing, this bearing can rotate along rotating shaft 18, and can endwisely slipping along rotating shaft 18.
In a preferred embodiment, the first friction wheel 11 is conical surfaces with the fitting surface of friction race 121, can adjust the moment of torsion that needs transmission by changing the taper angle of this conical surface, can suitably reduce the tapering of interior friction wheel taper hole face while needing to transmit compared with high pulling torque, vice versa.

In a preferred embodiment, transmission device can also comprise clutch and mounting plate 1, described clutch comprises the first engaging piece 15 and the second engaging piece 16, rotating shaft 18 is through described the first engaging piece 15, mounting plate 1 and the second engaging piece 16, the second engaging piece 16 is fixed on described mounting plate 1, the first engaging piece 15 and the second friction wheel 12 are relative fixing in the radial direction rotating shaft 18, and described the first engaging piece 15 can be along moving on the axial direction of described rotating shaft 18.When closed i.e. the first engaging piece 15 of clutch and the second engaging piece 16 are meshed, the first engaging piece 15 moves downward and is meshed with the second engaging piece 16.In a better embodiment, transmission device also comprises fixed plate 13, described the second friction wheel 12 is fixing with described fixed plate 13, described rotating shaft 18 is through described fixed plate 13, described fixed plate 13 is provided with fixed plate groove 131, described the first engaging piece 15 is provided with the projection coordinating with described fixed plate groove 131, described the first engaging piece 15 and described fixed plate 13 are relative fixing in the radial direction described rotating shaft 18, but rotating shaft 18 axially on can relatively move, thereby guaranteed that the first engaging piece 15 can move to the position being meshed with the second engaging piece 16.Clutch can be magnetic clutch, and the second engaging piece 16 has magnetic core, and the first engaging piece 15 is as armature.
In one embodiment, pass gates comprises above-mentioned transmission device, also comprises gate 19, and gate 19 is fixed in rotating shaft 18, preferably can also comprise an axle 20, and axle 20 is fixing with rotating shaft 18 and gate 19 respectively.
The transmission device of above-described embodiment, is not only applicable to pass gates, can also be suitable for other occasions, such as material transmission etc.
In one embodiment, the working procedure of pass gates is as follows:
Motor 2 drives speed reducer 3 to rotate and makes 5 rotations of speed reducer belt pulley, speed reducer belt wheel 5 rotates belt wheel 10 by belt 6, so belt wheel 10 is fixedly connected with moment of torsion is passed to the first friction wheel 11 with the first friction wheel 11, the male cone (strobilus masculinus) of the first friction wheel 11 coordinates the overall viewing range producing to rotating shaft 18 with the inner conical surface of the second friction wheel 12, main shaft 18 is about to moment of torsion and passes to rotating shaft 20, and main shaft rotates and drives gate 19 to rotate.When adjusting the elasticity dynamics of elastomer 8, in above-mentioned course of action, because gate 19 arm of forces are longer, when the opposing torque producing when gate 19 is met pedestrian is greater than the frictional force moment between the first friction wheel 11 and the second friction wheel 12, the first friction wheel 11 and the second friction wheel 12 produce and skid, the first friction wheel 11 is upwards thrown off and the compresses elastomeric 8 that makes progress, and then, motor 2 rotates the moment of torsion passing over and is disconnected between the first friction wheel 11 and the second friction wheel 12, so gate 19 stops operating, the moment of torsion passing over from input end on gate 19 also significantly reduces soon very much, thereby protect current pedestrains safety.When pedestrian stops stopper gate 19, pedestrian reduces even to disappear to the opposing torque of gate 19, and elastomer 8 recovers initial elastic state again, again makes the first friction wheel 11 contact and produce frictional force with interior friction wheel 12, and rotating shaft 18 is rotated.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to the utility model by the definite scope of patent protection of submitted to claims.
